The budget fight may be happening in Washington, but it’s investors on Wall Street who keep getting hurt.

U.S. stocks on Friday fell for the sixth day out of the last seven and ended the week with a decline. Investors focused on the risk that the government could shut down on Tuesday unless Congress agrees to a new spending bill. And even if that hurdle is cleared, the dispute is poised to continue into the middle of October as legislators debate raising the nation’s borrowing limit.

There were a lot of moving parts for investors to keep track of on Friday. The Senate approved a spending bill that is already considered dead in the House of Representatives, where Republicans want changes to President Barack Obama’s health care law. Obama spoke on live television during the closing minutes of trading. And investors braced for the possibility that when markets reopen on Monday, none of this will have been resolved, even though the House will be in session over the weekend.

So how should an investor get ready for next week?

“I don’t know what’s going to happen 15 minutes from now,” said Stephen Carl, head of equity trading at The Williams Capital Group. He noted that volume on Friday was low, suggesting that some investors were waiting for more information.

Stocks moved little as Obama spoke during the final minutes of trading. He reiterated a previous vow not to negotiate with Congress under the threat of a shutdown.

The Dow Jones industrial average fell 70.06 points, or 0.5 percent, to close at 15,258.24. The Standard & Poor’s 500 index fell 6.92 points, or 0.4 percent, to 1,691.75. The Nasdaq composite was down 5.83 points, or 0.15 percent, at 3,781.59.

Still, the indexes are off only about 1 percent for the week, and the S&P 500 is just 2 percent below its record high set Sept. 18.

Investors are also dealing with mixed economic signals.

On Friday, a government report showed that incomes and consumer spending grew slightly last month. The increases suggest anemic growth that is not strong enough to accelerate the economic recovery.

A survey showed that consumer confidence declined this month as Americans worried about the possible government shutdown and their own finances. The survey found that half of households expect no pay increase in the coming year.

The Federal Reserve’s view last week that the economy is still weak is scaring people, said Frank Fantozzi, CEO of Planned Financial Services.

“If you keep saying things are bad, even if things are good, people are going to believe they’re bad, and they’re going to act accordingly,” he said.

Eight out of 10 industry groups in the S&P 500 index fell. Health care and consumer discretionary stocks had small gains.

Among big stock movers:

∎ J.C. Penney Co. shares slid $1.37, or 13 percent, to $9.05 after the struggling retailer said it would raise about $811 million through a stock offering. The shares fell as investors noted that the new shares are priced at $9.65, less than J.C. Penney’s closing price of $10.42 on Thursday. Also, the growing pool of shares means investors’ current stakes in the company will shrink.
